Abstract
A compression device includes: a compressor including a casing, a rotor that is housed in a rotor chamber inside the casing and compresses gas by rotating, a bearing that is provided inside the casing and supports a rotor shaft so that the rotor is rotatable, and a first shaft-sealing part and a second shaft-sealing part that are provided to line up between the rotor chamber and the bearing in the casing to seal a periphery of the rotor shaft; a first supply line adapted to supply injection oil to the rotor chamber; a second supply line that is provided independent of the first supply line to supply lubrication oil to the bearing; a third supply line adapted to supply sealing gas to the first shaft-sealing part; and a fourth supply line adapted to supply the second shaft-sealing part with sealing oil to be used for sealing.
